  # Choose what kind of storage to use for this uploader:
  # storage :qiniu
  # storage :fog
  storage :file

  # Override the directory where uploaded files will be stored.
  # This is a sensible default for uploaders that are meant to be mounted:
  # def store_dir
  #   "#{mounted_as}/#{model.id}"
  # end
  #
  def store_dir
    "uploads/#{model.class.to_s.underscore}/#{mounted_as}/#{model.id}"

  # Provide a default URL as a default if there hasn't been a file uploaded:
  def default_url
    # For Rails 3.1+ asset pipeline compatibility:
    # ActionController::Base.helpers.asset_path("default_avatar.png")

    # "/images/fallback/" + [version_name, "default.png"].compact.join('_')

    # after upgrading sprockets-rails to 2.1.4
    # image_tag has prefix "assets/images/" and will throw error:
    # Asset names passed to helpers should not include the "/assets/" prefix.
    "default_avatar.png"

  end

  # Process files as they are uploaded:
  # process :scale => [200, 300]
  #
  # def scale(width, height)
  #   # do something
  # end

  # Create different versions of your uploaded files:
  # version :thumb do
  #   process :resize_to_fit => [50, 50]
  # end

  # Add a white list of extensions which are allowed to be uploaded.
  # For images you might use something like this:
  def extension_white_list
    %w(jpg jpeg gif png)
  end

  # Override the filename of the uploaded files:
  # Avoid using model.id or version_name here, see uploader/store.rb for details.
  # def filename
  #   "something.jpg" if original_filename
  # end
